Description

The present invention relates to a face shield, and more particularly to a face shield technology that is lightweight, has excellent visibility, can reduce the burden on the user for long-term use, and prevents splashing.

As a means of preventing the spread of the new coronavirus in 2020, not only medical personnel but also counter operations such as restaurants and entertainment facilities are wearing face shields to prevent splashing. Most of the conventional face shields are attached to the ears, hats, masks, etc., and the types that do not have other attached members other than the face shields are attached to the entire head or to the ears. Most of them are locked. Therefore, if it is used for a long time, problems such as pain in the head and ears are likely to occur. Further, if the mounting frame is present in the forward direction, the visibility is impaired, and if the frame is in contact with the frame, the shielding member may be clouded or it may become hot in the summer.

In addition, in order to reliably prevent infection by viruses and the like due to splashing, at least the shielding member must be replaced frequently. That is, it is expected to propose a new face shield that is easy to replace, can reduce the cost, and does not tighten the head.

Therefore, in view of the above problems, various techniques have been proposed conventionally. For example, the name of the invention is "face shield for surgery", and the problem to be solved is "there is no feeling of oppression or blockage when worn, the shield is prevented from fogging due to exhalation, and the mask or cap is still worn. "Provides a face protection shield that is extremely easy to put on and replace." The specific solution is "a shield that covers the face, folds that are bent at blunt angles at the left and right corners, and the tip of the fold." It is provided with a margin to which the adhesive tape is attached. The upper part is attached to the front face of the cap and the lower part is attached to the front surface of the mask by the adhesive tape. " However, such a technique is for surgery, in which a facial shield is attached to a cap or mask with adhesive tape, and cannot be attached without using a cap or the like. It differs from the present invention, which does not require a mounting member.

Further, the title of the invention is "a mask for preventing splashing", and the problem to be solved is "providing a structure of a mask for preventing exhalation and preventing splashing". "Consists of a frame, a shielding sheet and two vines, the shielding sheet is assembled on the upper edge of the frame, and the two vines are assembled on both ends of the frame. The shielding sheet shields the front of the user's mouth by hanging the ear hook on the user's ear. " However, since the technique is used by hanging the ear hook of the vine of the frame on the user's ear, there may be a problem that the ear hurts when used for a long time.

In addition, the name of the invention is changed to "face guard frame", and the problem to be solved is "a face guard that protects the face from blood and body fluids scattered during surgery and protects the face from other flying objects." The specific solution is to provide a frame. "The guard frame has vines on both ends of the front frame, and the surface of the vines leaves a slight gap between the surface and the surface." A holding piece is provided, two convex pieces are formed on the back surface of the holding piece at a predetermined interval, and a transparent plastic sheet capable of covering the entire face is placed on the front surface of the front frame, and the side ends thereof. Is sandwiched between the holding pieces and attached. " However, this technology also has vines from the front frame to both ends and is used by hanging it on the user's ear. As in the case of Prior Art Document 2, the problem that the ear hurts when used for a long time can be solved. It is not.

In addition, the name of the invention is "spray shield plate for painting work", and the purpose to be solved is "extremely easy to put on and take off, lightweight, surely protects the eyes from paint splashes, and if it gets dirty, it can be easily thrown away. However, we will provide a splash shield plate for painting work that is relatively easy to bear the financial burden. ”The specific solution is“ a transparent, flexible thin plastic with a curved front part and this. A clip that projects to the left and right from the upper edge and a clip that projects to the front are projected onto the curved shielding plate that forms the left and right side surfaces that follow, and the outer end of the clip is always the outer edge of the work cap's eaves. A splash shield plate for painting work that is configured by defining the curvature of the shield plate so that it is more inside. When the side part is opened a little and the clip is hooked on the cap of the hat, the shield plate tries to return to the original curvature. It is elastically fixed to the eaves and prevents splashes from getting into the eyes during painting work. " Although the technique is a splash shielding plate for painting work, it can be said that it solves a part of the problem of the present invention in that it is lightweight, disposable, and has a relatively light economic burden. However, since the invention is hooked to the eaves of the hat, a hat is required for wearing the hat, and it is considered that the configuration is different from that of the present invention which does not require such a wearable object.

It is the biggest feature. Hereinafter, description will be given based on the drawings. However, the shape and structure are not limited to those described in the drawings, and the changes can be made within the range in which the effect exerted as the creation of the technical idea of the present invention can be obtained.

1A and 1B are projection views for explaining a basic configuration of a face shield according to the present invention, FIG. 1A is a left side view, FIG. 1B is a front view, and FIG. 1C is a right side view. A top view is shown, FIG. 1 (d) is a bottom view, and FIG. 1 (e) is a rear view. The plan view is omitted because it is symmetrical to the bottom view.

The face shield 1 is a face shield 1 composed of a shielding member 10 and a frame 20, the shielding member 10 uses a transparent material 11 having an elastic force that returns to bending, and the frame 20 has a substantially elliptical shape. It has a mounting force adjusting subframe 30 on the head side and a gap forming beam 40 on the face side, and a mounting portion 50 for fixing the shielding member 10 to the tip end portion on the face side. The basic configuration is that there is nothing that comes into contact with the face surface. Hereinafter, each component will be described.

The shielding member 10 uses a transparent material having an elastic force that returns to bending, and the material is preferably PET (polyethylene terephthalate), PC (polycarbonate), or PMMA (acrylic), and the shape is preferable. Is not limited to the one shown in the figure, and may have an area that can cover the face with a substantially rectangular shape. Specifically, it is considered that a substantially A4 size is appropriate, and a clear file or the like may be provided with a mounting hole 60 instead.

As the transparent material 11, it is desirable to use a shielding member 10 having a high light transmittance in order to maintain a good field of view, and the transparent material 11 is appropriately selected in consideration of strength and cost. The typical materials will be described below.

PET (polyethylene terephthalate) 12 has a light transmittance of 87%, which is lower than that of acrylic, but has about four times the strength of acrylic, and it does not easily generate toxic gas even when burned, so it is also environmentally friendly. It can be said that it is a gentle material.

PC (polycarbonate) 13 has a light transmittance of 80% to 90%, has an impact resistance about 50 times that of acrylic, and can be made thinner due to its high strength, and is heavy. It is possible to reduce the weight.

PMMA (acrylic) 14 is a material having extremely high transparency and strong strength, with a light transmittance of 93%, which surpasses that of glass, and is also excellent in weather resistance and workability.

It is also effective to use PVC (polyvinyl chloride) in order to reduce costs. It has a light transmittance of about 80%, has excellent chemical resistance, and is a material that is not affected by most acids, alkalis, and salts.

The mounting position variable structure 15 is a structure in which the mounting position of the shielding member 10 can be changed with respect to the frame 20, and as shown in FIG. 4, the mounting portion 50 to be inserted into a plurality of substantially rectangular holes is mounted. By selecting the position, it is possible to adjust the mounting angle of the shielding member 10 and the distance from the face up and down or back and forth.

The frame 20 has a substantially elliptical shape that circumscribes the user's head, and includes a mounting force adjusting subframe 30 on the back of the head side, a gap forming beam 40 on the face side, and a mounting portion 50. The material is not particularly limited, but it is preferable to use ABS resin 22 from the viewpoint of moldability and strength.

ABS resin (acrylonitrile, butadiene, styrene, copolymer synthetic resin) 22 has the highest versatility among the resins, is superior in moldability, and is suitable for mass production by injection molding. In addition, it has excellent mechanical properties such as pulling and bending, and has good surface gloss, so that it is possible to obtain a high-quality texture without painting.

The mounting force adjustment subframe 30 reduces the weight of the entire frame 20 and weakens the mounting force only by the bending characteristics of the material of the frame 20 part. Therefore, the mounting force is compensated for and the mounting force is strengthened. Therefore, a subframe having a shape as shown in FIGS. 1 and 2 is provided. The presence of the mounting force adjusting subframe 30 makes it possible to firmly hold the frame 20 on the back of the head side.

The gap forming beam 40 is projected inward from the frame 20 in order to widen the mounting portion located at the front tip of the frame 20 to both outer sides near the temples and to keep a distance between the surface of the face and the shielding member 10. It is a beam.

The mounting portion 50 has a mounting structure for mounting the shielding member 10 on the frame 20, specifically, a protrusion having a substantially rectangular parallelepiped shape, and is inserted into a substantially rectangular hole formed in the substantially shielding member 10. It is a member to be fixed. The reason why it is not circular is to hold the fixed part in one place on each side.

The mounting portion hole 60 is a hole for fitting with the mounting portion 50 provided in the shielding member 10, and is formed in a substantially rectangular shape corresponding to the shape of the mounting portion 50. It is also preferable to provide a plurality of such mounting holes 60 so that the mounting position of the shielding member 10 can be changed.
